It's BT. Bacteria that gets in the guts of worms like vine borers and kills them quick.

I don't have the brand name in front of me. I got it at Lowes.

Injecting 4 acres of vines would be a serious PITA.

Okay. That is the same as Dipel(tm) gut wrencher BT. Perfectly safe for people.
And you are correct. I ain’t gonna crawl up and down four acres of vine. Summer would be up before I got to the end of the first row.
